and placing the enamel coated articles in the" fusing furnace is characterized. by many ditficultles and inconveniences which render most unsatisfactory, The devices now used for this vvorlr comprise louilt up holders WhlCl1 are stashed in tiers in a vertically superposed manner. lllach device consists of a multiplicity of bars, loops and risers. These are separate elements and must be assembled and disassemhled piece by piece for every load. For instance, first, the castings on the top tier in this assembling must he removed in order to permit access to he had to those on, the tier or raclt heneath then the castings on the middle tier are removed and this tier is disassembled piece loy piece, etc. The assem hling and reloading operation consumes much time and requires considerable shill and care in order to avoid the production of poor Work. The fact is that unusual care mus be exercised in these operations to u due spoilage, particularly Where multicolor coating enamels are employed.

Without delving further into the ditliculties experienced in the presentmet-hod of handling and stacking it is only necessary to say that the present one-piece tray has been especially designed with a vieW toward overcoming the objections and difficulties.

In. carrying the present invention into of test and practice I have evolved and produced a simplified and economical structure which is highly practicable in arrangement and such as to facilitate and expedite handling, assembling, disassemhling and other Work, thus the improved tray hotter fulfills the requirernent of this particular Work.

()ther -features and advantages will become more readily apparent from the following description and drawings.

Each tray as seen from Figures 52, 3, and 4: is in the form out an open vvorlr grid or trams structure. The parts are :t'ormed out chrome and niclrle or any other such metal or composition outlicient to Withstand the excessive hea i to prevent vvarpage While in the on furnace. lEach tray is generally by the reference character 7 an i in. l igure comprises longitudin" '1. side 8 connect d together h end hare in at om there are lfll'lglltmtul at intermediate oy ed parallel hers ill and transverse bracing; hare ll The lat er arranged in staggered relationship... All of the bars are substantially diamond shaped in cross section to provide the small est degree out contact with the enamel article (not shovvn). lln other WOIClS the contact surface between the tray and the article supported thereon is so made as to minimize the surface contact and to prevent marring oi the coated surtaces of the article. Attached to and rising from the opposite end bars 9 are short risers or posts 12 Whose upper ends are formed with V-shaped notches 13 to rece1ve the complemental end bars of the superposed tray as seen in Figure l. Tlhis per mits the tray to be stacked in the desired tier formation and prevents accidental displace ment and facilitates handlin From the foregoing description it will he seen that the gist of the invention is in the production of a one piece article carryinu tray oil appropriate proportion an d stren" the tray lacing composed oi metal one "will prevent distortion tvhile in the t'unaaco lil a side of one of the trays each tray being characterized by an open work. grid structure wherein the bar membars or castings to be moved, no danger of vantages accompanying the same.

rubbing of enamel or dirt to fall on lower tiers for each rack sets with its lower surface edges firmly seated in the risers of the adjacent tray beneath. Twenty-four to twenty-eight of these trays may be placed in the enamel furnace at one time on stove castings, such as for instance stove legs,

fronts, tops, doors, backs, or any other parts. It is entirely unnecessary for the burners and helpers to touch the castings. This efiects an unusual saving inotherwise destructed asbestos gloves that are burned up when handling hot castings piece by piece as in the old method. Thesetrays come direct from the drying process or graining process to the enamel furnace on platforms, are loaded on chargers and placed in the enamel furnace. In other words the work is allowed to remain on the trays during the various steps in the application of the coating material and the fusing as well as the spraying and other extra handling. If they come from the grainer, then they are placed on platforms to be taken into the inspector or packer or store room. There is no dumping about such as causes chipping and damaging of the enamel coating. All told, these one piece metallic trays will greatly expedite the handling of various types of articles. and will overcome the difliculties-and objections experienced in the old and seemingly crude method now followed. It is thought however that persons familiar with the old method and the improved tray will clearly appreciate the ad- Therefore, a more lengthy descriptionis regarded unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of invention may be resorted to in actual practice if desired.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is I 1. As a new product of manufacture, a one piece enameling tray composed of metal and including ahorizontal rack having a plurality of interconnected bars disposed in spaced relation, and integral vertically disposed supporting posts carried by the end bars of said rack.
